High output power was achieved by using the coupling technique of a laser diode array(LDA) and a micro-lensed fiber.根据808 nm大功率半导体激光列阵(LDA)的远场光场的分布特点,利用多模光纤柱透镜和光束转换装置对808 nm半导体激光列阵的发散角进行压缩整形,通过聚焦准直透镜将激光束耦合进入芯径为400μm的光纤,实现了30W的功率输出,其中最大耦合效率大于80%,光纤的数值孔径(NA)为0。yA1汉语字典

The principle of this technique is as follows: first linearly arranged beams are changed into circularly arranged beams by a fiber array so that the beam symmetry of a laser diode array can be greatly improved;then the circular laser beam from the fiber array is coupled into a single thin fiber by a micro-lens to reduce the beam diameter and improve its brightness.首先借助光纤列阵实现光束由线性排列到圆形排列的转换,从而有效提高半导体激光列阵输出光束的对称性;然后通过微透镜将光纤列阵输出的圆对称光束耦合进入一根较细的光纤,以进一步压缩光斑直径并提高光束亮度。yA1汉语字典

High-power laser diode arrays are difficult to use directly in such fields as military, industry, and medicine because of their extremely asymmetric divergent beams (θ_x≈5°～10° and θ_y≈20°～35° ), i.半导体激光列阵的输出光束有较大的发散角和较强的不对称性,极大地限制了其在各领域中的应用。yA1汉语字典
